6. Billing and Payment

Subscription Plans. The Services are offered under various Subscription Plans with differing features, usage limits, and pricing. Your Subscription Plan determines the fees applicable to your use of the Services. Current pricing is available on our website or in your applicable order form.

Month-to-Month Billing. Unless otherwise specified in a written agreement, all Subscription Plans are billed on a month-to-month basis. No long-term contracts are required. You may cancel your Subscription Plan at any time with thirty (30) days' written notice. Cancellation takes effect at the end of the current billing period.

Usage-Based Charges. Certain Services incur usage-based charges in addition to your Subscription Plan fee, including per-minute calling charges, per-message charges, AI unit consumption, add-on subscriptions, and additional user seats. Usage-based charges are billed monthly in arrears.

Payment Methods. You agree to provide a valid payment method and to keep your payment information current. Whistle may use third-party payment processors to handle transactions. By providing payment information, you authorize us to charge the applicable fees to your designated payment method.

Taxes and Surcharges. All fees are exclusive of applicable taxes, regulatory surcharges, and telecommunications fees. You are responsible for paying all such charges.

Late Payment. If any payment is not received by the due date, Whistle may charge interest on the overdue amount at the lesser of 1.5% per month or the maximum rate permitted by law. Whistle may also suspend access to the Services if payment remains overdue after written notice and a reasonable cure period.

Fee Changes. Whistle may change its pricing with at least thirty (30) days' prior written notice. Continued use of the Services after a price change takes effect constitutes your acceptance of the new pricing. If you do not agree to a price change, you may cancel your Subscription Plan before the new pricing takes effect.

Refunds. Prepaid fees are non-refundable except where required by applicable law. If Whistle terminates your Account without cause before the end of a paid period, we will provide a pro-rata refund of prepaid fees for the unused portion of that period.

7. AI Features and Data Processing

AI Processing. Whistle offers AI-powered features including call transcription, summarization, sentiment analysis, and intelligent routing. These features process Customer Data, including voice recordings and message content, using machine learning models.

Self-Hosted AI. Whistle's AI inference runs on dedicated infrastructure operated by Whistle. Customer Data processed by AI features is not transmitted to third-party AI service providers. AI processing occurs within the same infrastructure environment as your other Customer Data.

AI Output Accuracy. AI-generated outputs, including transcriptions, summaries, sentiment scores, and routing recommendations, are provided on an informational basis. While we strive for accuracy, AI outputs may contain errors, omissions, or inaccuracies. You should not rely on AI outputs as the sole basis for legal, medical, financial, or other consequential decisions without independent verification.

AI Unit Consumption. AI features consume usage units ("AI Units") as described in your Subscription Plan. Different AI actions consume different quantities of AI Units. Your Subscription Plan includes a monthly AI Unit allocation. Additional AI Units may be purchased as add-on packs.

Data Use for Improvement. Whistle may use de-identified and aggregated data derived from your use of the Services to improve the quality, accuracy, and performance of the AI features and the Services generally. Such aggregated data will not identify you, your Authorized Users, or your End Users. You may opt out of this use by contacting us at privacy@getwhistle.ai.

PII Redaction. Whistle provides an automatic PII redaction pipeline that can redact sensitive information (such as credit card numbers and government identification numbers) from transcripts and AI outputs before storage. You are responsible for configuring and enabling PII redaction features as appropriate for your use case and regulatory requirements.

8. Call Recording and Consent

Recording Features. The Services may include call recording capabilities. If you enable call recording, you are solely responsible for complying with all applicable laws regarding the recording of telephone conversations and other communications.

Consent Requirements. Many jurisdictions require that one or all parties to a communication consent to its recording. Requirements vary by jurisdiction and may include one-party consent, all-party consent, or notification obligations. You are solely responsible for determining the consent requirements applicable in your jurisdiction and the jurisdictions of the parties you communicate with, and for obtaining all necessary consents.

Recording Storage. Call recordings are stored in encrypted form within your Tenant and are accessible only to Authorized Users with appropriate permissions. Recordings are subject to your configured data retention policies. Default retention is ninety (90) days, which you may adjust within the limits of your Subscription Plan.

Whistle's Role. Whistle provides the technical capability for call recording. Whistle does not provide legal advice regarding recording consent requirements. You should consult with qualified legal counsel to understand your obligations.

9. Underlying Providers and Third-Party Services

Underlying Voice and Messaging Providers. The Services may rely on one or more underlying telecommunications carriers, voice providers, or messaging providers to deliver voice calling, PSTN connectivity, SMS/MMS delivery, phone number provisioning, and related capabilities. The specific providers used may vary based on your geographic location, Subscription Plan, and service configuration.

Provider-Specific Terms. Certain terms, including acceptable use requirements, number registration obligations, messaging throughput limits, and regulatory compliance requirements, may vary based on the underlying provider used to deliver a particular service component. Whistle will communicate any material provider-specific requirements that affect your use of the Services.

Third-Party Messaging Platforms. Integration with third-party messaging platforms (such as WhatsApp Business) is subject to the terms, policies, and acceptable use requirements of those platforms. You are responsible for complying with all applicable third-party platform terms in addition to these Terms.

Third-Party Integrations. The Services may offer integrations with third-party applications and services (such as CRM systems, collaboration tools, and automation platforms). Your use of third-party integrations is subject to the terms and privacy policies of those third parties. Whistle is not responsible for the availability, accuracy, or performance of third-party services.

No Endorsement. Whistle's integration with or use of any third-party service does not constitute an endorsement of that service.

10. Data Protection and Privacy

Customer Data Ownership. You retain all right, title, and interest in your Customer Data. Whistle does not claim ownership of your Customer Data.

Data Processing. Whistle processes Customer Data solely to provide and improve the Services. Our processing of personal information is described in our Privacy Policy, available at getwhistle.ai/privacy.

Tenant Isolation. Customer Data is logically isolated within your Tenant. Whistle's architecture enforces per-tenant data separation at every layer, including databases, caching, file storage, and AI processing.

Encryption. Customer Data is encrypted in transit and at rest using industry-standard encryption protocols. Call recordings and sensitive data are encrypted with per-tenant encryption keys.

Data Retention. You may configure data retention policies within the limits of your Subscription Plan. Upon termination of your Account, Whistle will delete your Customer Data in accordance with Section 13 of these Terms.

Data Portability. You may export your Customer Data at any time through the Services or by contacting support. Whistle will provide reasonable assistance with data export requests.

Compliance. Whistle is designed to support compliance with applicable data protection laws, including Canada's Personal Information Protection and Electronic Documents Act (PIPEDA) and the General Data Protection Regulation (GDPR) where applicable. We make data processing agreements available upon request.

11. Intellectual Property

Whistle's Intellectual Property. The Services, including all software, interfaces, documentation, designs, algorithms, and models, are the intellectual property of Whistle Technologies or its licensors. These Terms do not grant you any ownership interest in the Services. You are granted a limited, non-exclusive, non-transferable, revocable license to access and use the Services in accordance with these Terms and your Subscription Plan.

Customer Intellectual Property. Whistle does not acquire any intellectual property rights in your Customer Data, your trademarks, or your proprietary content transmitted through the Services.

12. Confidentiality

Confidential Information. Each party may disclose confidential information to the other in connection with the Services ("Confidential Information"). Confidential Information includes, without limitation, business plans, technical data, product information, pricing, Customer Data, and any information marked as confidential or that a reasonable person would understand to be confidential given its nature and the circumstances of disclosure.

Obligations. The receiving party agrees to: (a) use Confidential Information only for the purposes of exercising its rights and fulfilling its obligations under these Terms; (b) protect Confidential Information with at least the same degree of care it uses to protect its own confidential information, and no less than reasonable care; and (c) not disclose Confidential Information to third parties except to employees, contractors, and advisors who need to know and who are bound by confidentiality obligations at least as protective as those in these Terms.

Exceptions.

Compelled Disclosure.

Data Deletion. Following the thirty (30) day post-termination retention period, Whistle will initiate an asynchronous data purge of all Customer Data associated with your Tenant. Completion of the purge will be logged. Certain data may be retained longer where required by law (such as call detail records required for regulatory compliance).

14. Warranties and Disclaimer

Whistle's Warranty. Whistle warrants that the Services will perform materially in accordance with the applicable Documentation during the term of your Subscription Plan. If the Services do not conform to this warranty, your exclusive remedy is for Whistle to use commercially reasonable efforts to correct the non-conformity, or, if Whistle is unable to do so within a reasonable time, to terminate your Subscription Plan and provide a pro-rata refund of prepaid fees.

Your Warranty. You warrant that: (a) you have the legal authority to enter into these Terms; (b) your use of the Services will comply with all applicable laws and regulations; and (c) you will not use the Services in any manner that infringes or misappropriates the rights of any third party.

WHISTLE DISCLAIMS ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WHISTLE DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ALL DEFECTS WILL BE CORRECTED.

Emergency Services. THE SERVICES ARE NOT DESIGNED OR INTENDED TO BE USED AS A REPLACEMENT FOR TRADITIONAL TELEPHONE SERVICE FOR EMERGENCY CALLING (E.G., 911 IN NORTH AMERICA OR 112 IN THE EU). WHILE WHISTLE MAY SUPPORT E911 FUNCTIONALITY WHERE AVAILABLE, VOIP-BASED EMERGENCY CALLING HAS INHERENT LIMITATIONS, INCLUDING POTENTIAL INACCURACY OF LOCATION INFORMATION AND DEPENDENCE ON INTERNET CONNECTIVITY AND POWER. YOU SHOULD MAINTAIN AN ALTERNATIVE MEANS OF ACCESSING EMERGENCY SERVICES.

Exclusion of Indirect Damages. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER PARTY WILL BE LIABLE TO THE OTHER FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES, REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, STRICT LIABILITY, OR OTHERWISE) AND REGARDLESS OF WHETHER THE PARTY WAS ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Aggregate Liability Cap. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS AND THE SERVICES WILL NOT EXCEED THE TOTAL FEES PAID OR PAYABLE BY YOU TO WHISTLE DURING THE TWELVE (12) MONTH PERIOD IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

Whistle's Indemnification. Whistle will indemnify, defend, and hold harmless you and your officers, directors, employees, and agents from and against any third-party claim that your authorized use of the Services infringes or misappropriates the intellectual property rights of that third party, and will pay any damages finally awarded or settlement amounts agreed to.

The current version of these Terms is always available at getwhistle.ai/terms.

18. Governing Law and Dispute Resolution

Governing Law. These Terms are governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to conflict of law principles.

Jurisdiction. The parties submit to the exclusive jurisdiction of the courts of the Province of Ontario, sitting in Toronto, for the resolution of any disputes arising out of or related to these Terms.

The parties will use good faith efforts to resolve any dispute within thirty (30) days of receiving notice of the dispute.

Injunctive Relief. Nothing in this section prevents either party from seeking injunctive or other equitable relief from any court of competent jurisdiction to prevent irreparable harm pending resolution of a dispute.

19. Emergency Services and Telecommunications Notices

Not a Replacement for Traditional Phone Service. The Services use internet-based protocols to transmit voice communications. The Services may not support or may have limited support for emergency calling services (such as 911 in Canada and the United States or 112 in Europe). You acknowledge that the Services have inherent limitations for emergency communications, including but not limited to: dependence on internet connectivity, dependence on electrical power, potential inability to convey accurate location information to emergency dispatchers, and potential routing to different emergency call centers than a traditional landline.

E911 Compliance. Where Whistle supports E911 functionality, you are responsible for providing and maintaining accurate registered location information. Whistle is not liable for any failure or delay in connecting to emergency services.

Telecommunications Regulatory Notices. You acknowledge that the Services are subject to applicable telecommunications regulations in the jurisdictions where they are used.

Severability. If any provision of these Terms is found to be unenforceable or invalid, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect.

Waiver. No waiver of any provision of these Terms will be effective unless in writing and signed by the waiving party. A party's failure to enforce any right or provision of these Terms will not constitute a waiver of that right or provision.

Assignment. You may not assign or transfer these Terms or any rights hereunder without Whistle's prior written consent, except in connection with a merger, acquisition, or sale of all or substantially all of your assets. Whistle may assign these Terms without restriction. Any attempted assignment in violation of this section is void.

Independent Contractors. The parties are independent contractors. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between the parties.

No Third-Party Beneficiaries. These Terms do not create any rights for any third party, and no third party may enforce any provision of these Terms.

Force Majeure. Neither party will be liable for any failure or delay in performing its obligations under these Terms (other than payment obligations) due to causes beyond its reasonable control, including natural disasters, acts of government, pandemics, war, terrorism, labor disputes, internet or telecommunications failures, or third-party service outages.

Notices. All notices under these Terms must be in writing and will be deemed given when delivered by email (with confirmation of receipt), by nationally recognized overnight courier, or by registered or certified mail.
